My wife wants to add my nephew to our plan but he will need a new phone, his is a prepaid service that can't be used on T-Mo. he doesn't have credit (and I'm not paying for it) so he will use an older phone in the meantime. They told my wife he would have to be a customer in good standing in order to purchase or lease a new phone. Unfortunately she didn't ask how long you had to be a customer before your considered in good standing, does any one know? I'm guessing a year.
